UNITED STATES PATENT OFFICE.

JOSIAH FAHRNEY, OF WAYNESBOROUGH, PENNSYLVANIA.

SPECIFICATION forming part of Letters Application filed January 4, 1882.

Patent No. 254,810, dated March 14, 1882.

(No model.)

To all whom it may concern Be it known that I, J OSlAH FAHRNEY, acitizen of the United States of America, residing at Waynesborough, inthe county of Franklin and State of Pennsylvania, have invented certainnew and useful Improvements in Straw Carriers and Shakers forThrashing-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the 7 art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

This invention relates to shakers and strawcarriers which are applicableto thrashingmachines and separators. The following description of myinvention, when taken in connection with the annexed drawings, willenable others skilled in the art to fully understand it.

In the drawings hereto annexed, Figure 1 represents a vertical sectionalview through that portion of the separator which shows my improvement.Fig. 2 represents a cross-sectional view of the same. Fig. 3 representsa top or plan view, and Figs. 4, views.

.1 As my invention has reference only to the tail of a'grain thrasherand separator of the ordinary or well-known construction, I shallconfine my description to such part.

A designates the frame or housing, and B the guide-board leading to theshaker and carrier. Between this guideboard and a transverse.connecting-support for the checks of the I housing Isecureequidistantlyfrom each other bars 0, arranged in a plane incliningtoward the thrashing-cylinder, which I have not shown. The bars are madeby boring holes through a plank and then sawing the plank into strips,the kerf cutting diametrically through the holes. I thus leave openingsfor the passage of 5, and 6 are detail.

' and at the same time an impulse upward and toward the tail of themachine. Both ends of each barE have sliding strips F fixed to them,which are suitably guided. These strips, which may be made flexible,prevent the bars from binding and afford elasticity to the same, and atthe same time admit of the use of the carrier-pins, which I will nowdescribe.

G G designate cranked shafts which have many throws, and to the cranksof these shafts bars J are applied by means of caps K, into which pinsor studs a are fixed, protruding from the edges of the bars above theinclined board D, which, with the assistance of these pins, carries backthe grain and short straws, to be separated in any well-known manner.

H indicates a retaining-board hinged at the tail end of the carrier, andprovided on its upper face with beveled ridges h, for carrying off thestraw and what grain that may reach the same, to be carried back to theshaker.

To the under side of my new scalloped bars E, I secure strips 0 for thepurpose of strengthening said bars.

To the bars J, I suitably fix, at even distances apart, rake-teeth b,which extend upward and have free play through holes made through thebars E.

It will thus be seen by the above description.

that the bed of myimproved straw-carrier and grain-separator is composedof rigidly-fixed scalloped bars and intermediate longitudinally andvertically movable bars,which alternate in their upward and downwardmovements with respect to each other, controlled by the arrangement orthrow of their cranks, and give progressive tossing movement to thestraw, so as to shake from it the grains which remain in it whendelivered upon the shaker.

At the upper ends of the scalloped bars E, I secure beveled ridges c,which are inclined and directed upwardly, and immediately in rear ofthese ridged guides for the straw I fix wires d, which form bridges forthe straw on its way from the carrier-bed at the tail thereof. Thecurved wires d are rigidly secured at their rear ends to the upper endsof the scalloped bars 0, for the purpose of guiding or bridging thestraw from the carrier-bed over the space left between the upper ends ofsaid bars and the hinged edge of the board H and delivering the strawupon this board. This construction is clearly shown in Figs. 1 and 3.

Having thus described my invention, what I I claim, and desire to secureby Letters Patent,

1. An inclined straw-shaker bed consisting of fixed scalloped bars,intermediate vertically and longitudinally reciprocating bars, carryingteeth vertically movable through the latter, and ribbed inclined guidesat the upper or tail ends of the fixed or scalloped bars, substantiallyas described.

2. In astraw-shaker, the combination of the fixed scalloped bars, theintermediate endwisereciprocating bodily-moving bars, cranks foroperating said bars, and the rakingteeth b, vertically movable throughthe reciprocating bars'by means substantially as described.

3. The combination of the wire bridges d, the scalloped fixed bars 0, towhich these bridges are secured, the endwise and vertieally movable barsJ, rake-teeth I), mounted thereon, and the bars E, substantially asdescribed.

4. Thecombination otthe board H, provided with ribs h, the scallopedbars 0, the bridgewires d, extending from these bars over the said boardH, the guide-bars E, and rakingteeth 1), operating substantially asdescribed.

In testimony whereofI attix my signaturein o presence of two witnesses.

JOSIAH FAHRNEY.
